The snow comes down as 60,000 fans pack into Soldier Field for a rare outdoor Blackhawks hockey game.

And after the snow, more cold is on the way.

"Most of the system snow will be out of here shortly after daybreak, and even earlier than that if you're in the city and points north," said ABC7 Eyewitness News meteorologist Phil Schwarz.

Freezing rain and sleet are also in the forecast. Cities have mobilized snow removal crews as the National Weather Service cautions that travel could be hazardous.

A winter weather advisory was issued for 3 p.m. Saturday to 9 a.m. Sunday, and until noon in northwest Indiana.

"The snow will move from the northwest and gradually sag to the southeast," said ABC7 Eyewitness News meteorologist Phil Schwarz. "All of the snow is moving east at around 30 miles per hour. We will have several hours of snow, there will be some significant accumulations, most of us will see 2-6 inches."

The snow could also create other problems on the roadways, and at times snowfall rates could reach up to an inch an hour. Drivers should plan accordingly, and be prepared to slow down and give snow removal equipment room.

According to the National Weather Service, snow should taper off by Sunday morning, although some lake effect showers may linger over far northeastern Illinois.
